Burger King's Impossible Whopper is arriving at over 100 locations in the San Francisco Bay Area.
The meatless burger, which features a patty made by the plant-based protein company Impossible Foods, is already available in Miami, Florida; Columbus, Georgia; Montgomery, Alabama; and St. Louis, Missouri, where the burger was first tested.
Burger King plans to sell the burger nationally by the end of the year.
The San Francisco roll out marks a significant increase.
Until Monday, about 200 locations in those four markets served the product.
